IDS GeoRadar facts
• Leader in Multi-frequency, Multi-channel Ground Penetrating Radar Systems
– IDS began to study GPR technology since 1991 in connection with the need of Telecom
Italia of improving the capabilities of mapping subsoil Utilities
– IDS was the first to introduce in GPR market the multi-frequency, multi-channel array
systems, dramatically improving utilities detection performance

9. GeoRadar
Utility Mapping
Technology principles (1/4)
The radar transmits a small pulse of
EM wave through an antenna
The reflected energy from the
discontinuity is captured and
received by the antenna.
The time delay contains information
on the target depth
The depth and the resolution are
related to the antennas frequency,
to the power transmitter and to the
dielectric properties of the ground.

Utility Mapping
Technology principles (2/4)
The GPR is a method developed for shallow, high-resolution, subsurface investigations
of the earth. GPR uses high frequency pulsed electromagnetic waves (from 25 MHz to
2,000 MHz) to acquire subsurface information.

Utility Mapping
The use of utility locating technologies
The cause of many accidents during excavations/DD installations is a lack of
knowledge of the subsoil conditions
A 36-fiber optic cable can carry up to 870,912 circuits and generate more than
$175,000 per minute in revenue
In 2003, there were in the U.S. more than 104,000 hits or third-party damage to
gas pipelines

affected 600,000 - 900,000 customers
1998 - US West cable network damage can exceed 2000/month hits (averages over 1.000/m hits)
1999 - A phone utility hit in Colorado cut off service for 12,000 customers.
1998 - A 36 fiber, fiber optic cable can carry up to 870,912 circuits, and can generate over $175,000 per
minute
1993 - More than 104,000 hits to gas pipelines with a total cost exceeding $86 million.
1997 - Memphis Light, Gas and Water paid damages of $515,000 and collected damages of $793,000 for
utility damage.

Regulations allows the setting of standards for appropriate and professional
engineering procedures.

and Depiction of Existing Subsurface Utility Data).
JUPEM: Standard Guideline for Underground Utility Mapping (AM/FM Technical Sub-
Committee & National Mapping and Spatial Data Committee).
NORMA ITALIANA CEI 306-8: Italian Regulations for performing preliminary surveys with
Ground Probing Radar before laying underground utilities and infrastructures.

Why use GPR technology?
GPR can locate any pipes: metallic and no-metallic, (PVC, concrete, etc.).
GPR allows the optimization of excavations / destructive testing and reduce
their costs and associated Risks.
GPR complements the surface inspection with an economic, objective,
documentable, precise (quantitatively interpretable) image of the
underground providing 100% of project area coverage.

Utility market needs
• Mark out Survey
– If the contract requires an ‘on
site mark up’ of the utilities
found then no permanent
record is provided.
• Recorded Survey
– Where a full record of the
survey results are to be
supplied this can be done
digitally ( CAD-GIS format ).

WHY AN ARRAY OF ANTENNAS?
Using an array of antennas it
is possible to correlate
Single antenna information coming from
several data channels.
It helps to accurately
reconstruct the path of
underground utilities in
complex situations.
An array scan cannot be
equivalent to many single

has more accuracy and

Retrieve information
Each utility coordination project begins with an initial investigation.
Once base plans are produced, detailed coordination begins, including
negotiating with all entities involved in the project.
• Identify utility owners that have facilities on,
or may be affected by, the project.
• Contact these utility and obtain existing
utility information from other sources.
• Make field observations to identify visible
above-ground utility features. Survey and
plot resulting information.
